Sarina, a citizen of 'the United States, residing` at the city of Janesville, county of Rook,A Stat-e of Wisconsinphave invented certain new and ,useful Improvements in Tractitm-Engines, of Which the following is a speciiication.

This inventionrelates to improvements in traction engines.

4 to anitnproved third Wheel iory traction engines, and is especially vdesigned by ine for .use -in my improved traction enginev illustrated and vdescribed -in my application for iti Letters Patent'led July l5, 1910,;Ser. No. 572,157, of Which application this lis a division, although .it isjreadily adapted` for use in other relations;

The main' objects of this invention are to provide. an improved third Wheel` lfor traction engines, which 1s so mounted as to permit its beingswung to eithervlside outol:` Way of thedravv baror chain, and held in" such position,'jor' 'can be used as a` caster Wheel, or for steering,` `or adpisted to an inoperative position `When not needed as al support, asis'the'case Where the vehicle or y tenslon ld, which` 1s arrangedin a suitable implement fto which the engine is hitched forms a partiof thev support lfor theY engine frame.

. Further "objects,v 4anal objects relating to structural detailswill definitely appear from the detailed description to followf .l 'aooomplishkthe l b iectsof my invention i by' thefdevioes and vmeans described in the followings specification. The invention is clearly diened"`and pointed ont in the claims.

A structure which isla preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming; au

part of'this invention, in'w'hich:

Figure l is a siede elevatlonof a structure embodyingthe features of my invention, ,the vengine proper being omitted and other parts 'being shownflargely in conventional form.

Fig. Il is a plan View of a structure appear# ing in-Fig. ll, the draft4 device there shown" being omitted and the third wheel shown?ad# justed toone side and into aninoperative .3 -3A ot Fig'. il. la?. ,the drawing, similar reference charac.

My present invention relates particularly ters refer to similar parts throughoutthe j -PatentedNov.'19,1912. thisnappIica-tion filed l1\T over nl er several views, andthe sectional views are4 shown" largely inconventional ifo-rm,- as are' lalso the traction Wheels 2 and the axle The 'traction wheel structure 1 isv preferably that shown andclairned in my application for Letters Patent. hereinbefore referred'to.

The draft or 'hitch device 4 is that `described in my said application, and described in detail and claimed in a divisional application filed concurrently herewith. L The third or caster Wheel 5 is provided With.

a yoke-like support -or standard 6 having a vertical spindle 7. The bearing 8 for this which is secured to the iframe by the verticalV Yspindle :is-slotted at 9, and'provided with a pivot bolt l2. This arm is arranged bef I tween the two frame-pieces 13 so that by tighteningthe bolt', the arm is clamped `to adjustably secure The-bearing 8 is provided with a pivot exsocket vl5- in the arno,` 11,'and the arm is `slotted,longitudinelily at `16 to permit its being clamped upon the pivot by ineens of the' clamping bolts' 17. By adjustingv this 1 clamping bolt and the bearing, the third' wheel is supported in its operative'` or .-up#

right position, .oiirnay'be supported in an in'- y operative p'0sition,.thatis, swungup to vthe horizontalposition,, asshown by dotted lines in Fig. II. Byadjustingthe clamping bolt 12, the' arm-'1l may vbe supported -in the position indicated by dotted lines in' Fig. Il, 1n vwhichv position 'itis out ofthe Way of the draftv or 'hitchl device .4; or the centrally connected draftnchain or bar.

` The spindle 7 isprovided with a steering lever 18, so that-thethid -Wheel is adapted to-.serve 1asasteering wheel, when desired." By thusfj arrangingJI .the parte,` the third Wheel maybeadj'usted to 'permit the ngineb'ein'g attaclziedl to a vehicle or imple jment by means of draw baror chain, and fthe third Wheel svi/ung out of operativepo;

sition when the vehicle. or implement serves asa supportfor the rear portion of the' trac- F tion frame, as described in my said copending app'licaton on the hitch'or draft device.

l`,I have illustrated molde-scribed my im; provements in detail 1n anl embodiment which is simple and desirable. I am aware,

however, that my improvements are capable ofpvery vgreat modifications 1n strnctural vde'- tailswithout departingfrom my invent-ion,
